In the cross field of biotechnology and organic acid preparation, centrifugal solvent extraction technology with its unique advantages is gradually becoming the key process means to prepare lactic acid, citric acid, succinic acid and other organic acids. Especially for citric acid, an important organic acid, its efficient and environmentally friendly extraction process is of great significance for improving product quality and reducing production costs. In this context, the combined extraction centrifugal extractor successfully replaced the traditional extraction equipment with its excellent centrifugal separation performance, and greatly improved the extraction efficiency of citric acid.

Citric acid, as a widely used organic synthesis raw material and acid flavor agent, its chemical structure (2-hydroxypropane-L,2, 3-tricarboxylic acid) gives it rich properties and a wide range of applications. Citric acid and its salts play an irreplaceable role in many industries such as food, medicine and industry. However, the traditional citric acid extraction process often has problems such as low efficiency, high energy consumption and large pollution, which limits the expansion of production scale and effective cost control.

To overcome these challenges, researchers are constantly exploring new extraction technologies and devices. The combined extraction centrifugal extractor, as the best of them, realizes the rapid separation of solvent and solute in the extraction process through its efficient centrifugal separation mechanism, thus significantly improving the extraction efficiency and purity of citric acid. In addition, the equipment also has the advantages of simple operation, high degree of automation, easy cleaning and maintenance, further reducing the production cost and labor intensity.

In the process of citric acid extraction, the application of combined extraction centrifugal extractor is not only limited to the basic extraction operation, but also involves the development of new complex extractant, the optimization of extractant and the fine control of process parameters. The research progress in these aspects, and the excellent performance of the combined extraction centrifugal extractor complement each other, and jointly promote the continuous upgrading and improvement of citric acid preparation technology.

The application of the combined extraction centrifugal extractor in the field of bio-organic acids, especially in the preparation process of citric acid, not only greatly improves the extraction efficiency, but also promotes the green, efficient and intelligent development of the entire production process. With the continuous progress of technology and the continuous expansion of the market, the combined extraction centrifugal extractor is expected to play an important role in the preparation of more organic acids, contributing to the deep integration of biotechnology and organic synthesis.
